7mm 0.15 pure nickel 8A continuous?

The common high capacity cells (35E, GA, MJ1) are rated at 10A continuous, however...I consider 10A to be their peak rating, if you want these cells to last a long time. When an ebike accelerates, that is when the pack experiences the peak demand. A 4P pack of 10A cells should be able to provide 40A without getting too hot.
However, after just a few seconds of acceleration, most ebikes attain a cruise speed where the amp demands slide down to a lower level, often 1/4th of the peak demands. When riding through a city and going from one green light to the next red light, you might accelerate for 2 or 3 seconds, and then the rest of the time you are riding, the ebike might experience 10A (2.5A per cell) to maintain speed.
0.15mm thick nickel is absolutely fine for the parallel connections, but for the series current of 8A per cell, I would never recommend 0.15mm for a continuous 8A per cell...
